Wire run behind refrigerator?

[JeffPatton]

I have a Wildcat Maxx 24RG and am installing solar panels and a rear-view camera up on top. I need to route the wires down and forward, and I'd heard that they can be run down through the rooftop refrigerator vent, behind the fridge, then down through the floor to the underside of the trailer. Has anyone done this? Some questions:

1. I assume I'm going to need to clad the wires to prevent being cut on the opening to the vent? The vent edge may be sharp.
2. When the fridge is running on propane, isn't there a risk of the exhaust heat damaging the wire insulation?
3. Is it a clear run? Can I run the wire down through the rooftop vent all the way to the floor beneath the fridge, without removing the fridge?
Thanks,
Jeff

Don't know how your roof is set up, but I ran my cables down alongside of a tank vent. Removed cap around pipe and it was a direct shot down underneath camper. If your bathroom is forward, should be a vent pipe to your black tank, that is what I used. Had a short piece of cable on roof, used Eternabond tape to fasten down.

With the fridges I have seen there is plenty of room for a wire to be run. The exhaust vent does not get hot, just warm as it it not only vents the propane exhaust, it also is air circulation for the cooling fins back there. Just be sure to run the wire down the side of the opening opposite the burner. Cladding the wire is a good idea.

I ran my solar wires that way and wires for a reefer fan. Lots of room.

I installed rubber grommets in the fridge vent to protect the wires.
